NCT Search 3.0 -- First MAJOR test in progress and it looks great

By Andrew Pollack on 02/15/2004 at 10:53 PM EST

Its an exciting day for me, because at long last NCT Search 3.0 is in a real serious QA mode. Right now, I'm hammering on it with 20 concurrant sessions, each posting search after search after search (10,000 times) without pause. What I'm looking for, is under those conditions do I loose memory, does the performance degrade to unusable levels, or does it just plain crash? So far, 30 minutes in, its looking rock solid. Memory usage is holding steady and average response time is hanging in around 45 seconds. Now, 45 seconds is a LONG time to wait for a search -- but if you understand concurrancy and do the math this test is roughly the equivilant of a server handling something close to 50,000 searches per day -- which is pretty big. This is a dual processer 700mhz machine (a speed daeman in its day) :-) --- but not something you'd host a site that big on. I'll be happy if it doesn't melt under that load. Regular use response times are ending up around 3 seconds which is very workable.

Wish me luck!


ohh....followup -- It looks like Tomcat is only using 1 of the two processors to do this. I can tell, W2K says that processor is just pegged at full for 'java.exe' lol. The other process is free for my Domino server. That bodes well for performance on faster machines. A single 700mhz machine doing this is COOL.

The truth is, I haven't had much to say that was worthy of more than a basic social media post -- until today. For my current work, I was assigned a new laptop. It's a real powerhouse machine with 14 processor cores and 64 gigs of ram. It should be perfect for running my development environment in a virtual machine, but it wasn't. VirtualBox was barely starting, and no matter how many features I turned off, it could ......

Certainly it should have been addressed in the Trump, Obama, Bush, Clinton, Bush, and Reagan administrations -- all of which were well aware of the implications of a pandemic. I want a military prepared to help us, not just hurt other people. As an American I expect that with the ridiculous funding of our military might, we are prepared for damn near everything.

This is not quite a scam because it's technically legal, but it's run very much like a scam. This company works with a few "clients" that have vast repositories of copyrighted images. The trolls do a reverse web search on those images looking for hits. When they find one on a site that looks like someone they can scare, they work it like ......
